MERCADO, JULIE ANNE F. Phytochemical Screening of the Purified Extract from Bunga de Jolo (Areca catechu Linn.) Fruit Pulp. Applied Research (General Science Curriculum). Cavite State University, Indang, Cavite. April 2006. Adviser: Mr. Rene B. Betonio and Research Teacher Edna A. Vida.
The research study was conducted at PSL5 Laboratory Room in the Department of Physical Science Building, College of Arts and Sciences Cavite State University Indang, Cavite from December 2005 to February 2006. The study aimed to characterize the active constituents from the purified pulp extract of Bunga de Jolo (Areca catechu Linn.) through phytochemical screening.
Twenty-five kilograms of Fresh Bunga de Jolo (Areca catechu Linn.) fruit pulp
was extracted and the constituents were isolated from the pulp by extraction with ethanol and chloroform. The yield of ethanol and chloroform extract was 7.6 percent and 5.9percent, respectively. The CHC13 extract was purified by column chromatography and the eluents collected were subjected to Thin Layer Chromatography (TLC). It underwent phytochemical screening for alkaloids, cardiac glycosides, saponins, tannins, anthraquinones, and flavonoids.
The results showed that Bunga de Jolo (Areca catechu Linn.) Fruit Pulp contained five (5) fractions, which were subjected into phytochemical screening characteristics to detect the presence of important biologically active compounds. The results revealed that all fractions contain alkaloids, which are responsible for its pharmacological actions, andcardiac glycosides that induce heart blockage. These results also showed that fractions 2 and 5 contained saponins using Froth Test, while fractions l , 2, and 4 contained saponins through Liebermann-Burchard Test; while tannins, anthraquinones and flavonoids are absent in all fractions.
